The NVIDIA NV48 - the NV45 with 512MB RAM

NVIDIA is planning the NV48, these graphics cards will be similar to the GeForce 6800 Ultra but will have 512MB RAM.

The clockspeed will remain the same as the GeForce 6800 Ultra - 400MHz core and 1100MHz memory.

NV48 will keep the Geforce 6800 series name and if we talk about the NV48 Ultra we will end up with 6800 Ultra 512 MB card. Gainward already announced such a card and it hopes to demo it at the soon to be upcoming CeBIT, or hangover as my dad says.
